Thanx. This is exactly what I was trying to say. I suppose the way to
think about it is that a parallax corrected range finder can look over
things that the tanking lens cannot. But why couldn't Ansel buy a
paramander or crank his tripod up the 1-1/2 inches? For hand holding,,
with a little thought, he could teach himself to compose with a 1-1/2
inch bend in his knees.

It's more the difference in the position of objects relative to each other (perspective) that is of more concern shooting a TLR close in than the error in framing (which is what the correction tries to compensate for). The paramender device Mamaya produced that you describe corrects for the perspective/parallax error. A. Adams was bothered by this and avoided TLRs and rangefinders because of it... Eric Goldstein

I'm puzzled by all the ingenuity spent on parallax correction. It seems easy enough to just aim a bit high, 1-1/2 inches on my Yashica. .
Most parallax correction contraptions are a bit of a makeshift.. Since the viewing lens is a bit higher it looks over things that might block the view of the taking lens. The Mamiya folks solve this with a device that fits between the camera and the tripod, that will jack the taking lens into the same place as the viewing lens. I have taken advantage of the bellows of a Mamiya to make 6x6 macro pictures by making pencil marks on the tripod. This wouldn't work if the camera had parallax control.
